Growth and Distribution: A Neoclassical Kaldor-Robinson Exercise

Tobin, James - Cowles Foundation for Research in Economics, Yale University - 1990

Kaldor's capital/labor income distribution theory relied on differential saving propensities from profits and wages. Robinson's growth models typically specified constant-coefficient technologies in which marginal productivities cannot determine distribution. Here these two insights are combined...
